Every figure below is transcribed from the paperwork for this compound.
Arginine replaces glutamate at position 3, and a 13-residue extension is added at the N-terminus. Both changes reduce binding to the IGF-binding proteins that would otherwise sequester the molecule, so a greater share of it stays free in solution. That is the entire point of the LR3 designation: Long, and R at position 3.
The batch information was easy to verify and the items were packed securely. The outer box had a small dent, but the contents were unaffected. It was a smooth experience for a research-supply order.
The GHK-Cu vial was labeled clearly and arrived protected. I had to click around briefly to find the batch certificate, but once there the information was easy to read. Overall, the receiving process was easy to document.
CJC-1295 arrived with a clear batch number, and finding the matching certificate was straightforward. The vial label was clean and easy to read. That level of organization is useful when cataloging incoming materials.
The parcel arrived safely and the contents were organized. Shipping communication was adequate, though an extra dispatch-status update would make it even better. The focus on traceability was noticeable throughout the process.
